The effect of dupilumab on caregiver- and patient-reported outcomes in young children with moderate-to-severe atopic dermatitis: Results from a placebo- controlled, phase 3 study

Background: Moderate-to-severe atopic dermatitis (AD) greatly impacts children/caregivers. Objective: Evaluate the impact of treatment with dupilumab on caregiver- and patient-reported AD symptoms and quality of life (QoL) in young children. Methods: In the LIBERTY AD PRESCHOOL (randomized, placebo-controlled) study, children aged 6 months to 5 years with moderate-to-severe AD received dupilumab or placebo plus low-potency topical corticosteroids for 16 weeks. This posthoc analysis assessed the change from baseline to week 16 in caregiver-reported outcome measures of AD symptoms (eg, itch and sleep) and QoL of patients and their caregivers/families. Results: Dupilumab (n = 83) vs placebo (n = 79) provided significant improvements in caregiver-reported AD symptoms and QoL. Significant improvements were seen as early as week 4 and sustained through the end of the study. Additionally, dupilumab vs placebo provided rapid and significant improvement in QoL measures for the patients' caregivers/families. Limitations: Few patients aged < 2 years; significance only reported for prespecified endpoints; Infant's Dermatitis QoL Index severity strata adopted from Children's Dermatology Life Quality Index. Conclusion: Dupilumab improved AD symptoms and QoL in patients and their caregivers/families.
